On his return to Japan twelve months later he found that his feudal chief, the dai-mio of Cho-shiu, had become involved in a dispute with the Bakufu, or Government of the Sho-gun, concerning right-of-way through the Shimonoseki Straits, which separate the Cho-shiu territory from the adjoining island of Kiu-shiu. The lord of the province was averse to the free entry of foreign vessels into the Inland Sea from the west, and had signified his disapproval by firing on ships that attempted the passage of the straits, from batteries which he had placed on the hills above. The Bakufu had failed to convince the Cho-shiu chieftain that the channel ought to be open to all comers, and despairing of its own ability to put a stop to the systematic interference with foreign shipping, had authorised the admirals of the Western Powers to take such measures as they thought fit. Ito Shunsuke, with his knowledge of the naval and military strength of the Occident amplified by personal inspection at the European capitals, saw that his lord was inviting disaster by his arbitrary treatment of the strangers, and sought to dissuade him from continuing the attacks on passing shipping, but the feudal baron was resolved to persist in his endeavour to check the influx of foreign ideas, and Ito had to return to the ship in which he had taken passage, with this express object in view, from Yokohama, with his mission unfulfilled. The foreign men-of-war had been at the time assembled in Yedo Bay preparatory to setting out for the Inland Sea, on their way to the Shimonoseki Straits to engage the Choshiu batteries, and the two young men of that province, for in this matter Ito was associated with his fellow-clansman Inouye, deemed it expedient to endeavour to convince their lord that however skilful might be the Choshiu gunners, it would be impossible for them to hold their own against the formidable armaments of the Western warships. In this long and self-imposed, and, as it turned out to be, useless journey to the capital of his native province from the coast, Ito was accompanied by this friend and fellow-student Inouye, who had likewise been to Europe with him,—no other than the present Count Inouye Kaoru, who is elsewhere referred to in this book.
